The VPAC includes the following
processing and infrastructure sub-modules:
- Vision Imaging Sub-System (VISS).
The vision imaging pipe does image processing on raw data which includes Wide
Dynamic Range (WDR) merge, Defect Pixel Correction (DPC), Lens Shading
Correction (LSC), Global/Local Brightness and Contrast Enhancement (GLBCE),
demosaicing , color conversion, and Edge Enhancement (EE). It can operate on
sensor data either on-the-fly or in memory-to-memory mode. The VISS provides the
following main features:
- Performance is 1 pixel
per cycle
- Up to 16-bit input RAW
formats (8b, 12b, 14b, 16b)
- Support for concurrent
12-bit and 8-bit YUV output
- Support for generic 2x2
RAW format (Bayer, RCCB, RCCC etc.)
- Support for other color
spaces:
- RGB output
- Support for color
saturation and gray scale for HSV/HSL, etc. (Hue is not
